Custom Class

[Anonymous]

In ObjectARX, I am able to create a custom class(CustomEllipse) by deriving
from an existing Autocad class(ex: AcDbEllipse). How do I create a custom
class(CustomBox) by deriving it from a class I create(Box)? Is there a way
to register a new class(Box) with Autocad?

All graphical objects must derrive from AcDbEntity or another class derrived
from AcDbEntity. Just override worldDraw() in your new class to display it
in the drawing.
